Be it known that i, Hanauer O. Carreau', citizen of the United States,residing at Sanford, in the county of Orange and State of tv Florida,have invented certain new and useful Improvements in Toot-hed Spikes, ofwhich the following is a specication.

This invention comprehends certain new and useful improvements in spikesdesigned particularly for use in securing railway rails .fte ties, andthe invention has for its ri mary object, a sim le, durable andeiiicient vnyconstruction of rai way spike, the parts of which are soarranged that the s ike maybe e'ectually l prevented hom becomingloosened acciden- A tally, while at the same time permitting it to beretracted whenever desired With this and other objects iii view as willfully appear as the description proceeds, the invention consistsessentially in a spike embodying a body portion with a ri penetratingtoe or point and head, and a ocking member pivotally connected to thespike and so arranged 'l' ber will be engaged with the base ange of jythe rail and thereby impart a tilting move- 3 mentY to the lockingmember so as to force I the toothed portion thereof outwardly into rmengagement with the tie, the teeth of such portion of the locking memberbeing tuallv upwardly beveled as shown so as to eii'ec prevent theretraction of the spike p without first tilting the locking` member to asition where its toothed edge or edges lie flush with the side edges ofthe body portion of the spike. And the inven- 74 tion also consists incertain constructions, arrangements and combinations ofthe parts Y thatshall hereinafter fully describe and claim. For a full understanding ofthe invention, refereixce is to behad to the following description andaccompanying drawings in which: Figure 1 is a side elevation of a spikeconstructed in accordance with my invention, 5 the same being shownpartly driven into the tie; Fig. 2 is a similar view with the spikelocked in the tie; F ig. 3 is a perspective view i ofthe spike; Fig. 4is a side elevation, partly broken away or' a. modied form of spike; 55.and, F ig. 5 is a transverse sectional view of y suchmodisedfem.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawingsby the same reference characters.

The body portion l of the spike is formed with the usual head 2 and witha penetrating toe or point 3. The main body portion 1 of the spike isrecessed in its side edges as indicated at 1i, roin a oint near the toe3 65 to a oint near the hea 2, for the rece tion of si e bars 5 of al O'member, sai side bars embracing the bo y portion of the spike and beingpivotally connected thereto intermediate ot their ends by a rivet 6 or70 similar fastening device. The side bars 5 of the lo 0' member are ofa width equal to or less than the width of the body ortion 1 so that thesideedges of said si e bars will not project beyond the margin of thebody portion when the locking member is arranged with its side bars inlongitudinal alinement with the body portion of the spike. The side bars5 of the locking niember are filned gypte tte ppt il amid2 on 80correspon ge switivy rge upwardly facing and preferably beveled teeth 7and may also be provided below the i pvot 6 and on correspondinglyopposite e teetiis 8, both sets of teeth being designed to embedthemselves into the wood of the tie when the locking member is tiltedrelative to the bod tportion 1.l 1n the inoperative position o e ends ofthe side bars 5 preferably lie close to the lower end walls o the recess4, ush with the shoulders formed by the upper end of the toe 3. t

The locking member includes addition to the side bars 5, a part orportion which is preferably formed integral therewith and which in theinvention now being described is in the form of abail or loop 9 which isdesigned to artially encircle the head 2 of 100 the spike w `ch isnormally oiiset therefrom as clearly illustrated in the drawing. Whenthe side bars 5 lie flush with the side edges or margins of the bodyportion 1, the bail or loop 9, which is angularly disposed to the sidebars 5 preferably lies in a plane ust slightly below the plane of thehea 2 whereupon when the spike is driven nearly home, the bail willengage the adgacent base flange of the rail and will consequently rockthe lockina member in a osition to project the toothed edges thereo theteeth ,A

. of the spike. y ,A f Y In that form of the invention illustrated 5 inFig. d 1* designates the body portion of the spike, the saine beingformed with a longitndinal slot l?. extending therethrough trom ont torear, and the locking member Y embodies a single bar 5* pivotallymounted 10 intermediate its ends as indicated at 6* in said slot. Theopposite edges of the bar 5* are toothed or notched as indicated at 7vand 8* respectively and the upper end `of the bar 5 is formed with aproiecting portion in the form of a tongue 9* designed to exltendunderneath the head 2*, and thereby ada ted to rock the locking member.

rom the foregoing description of the y construction and o ration'o thatform of i Y20 the invention which was rst above de scribed, togetherwith the accom anying i4 drawing, the operation or practi use of theisst described form will be apparent. f While I have shown or describedtwo y 25 forms or embodiments of the device, it is obvious that myinvention is not limited thereto, but that various changes or modifilcations may be made in the construction, arj' Arangement and proportionof the parts with- 30 ont departing from the spirit of the invention asdened in the appended claims. y l v As the locking member in eachinstance, is, l in the preferred construction of parts, pivotallyconnected intermediate of its ends to the body portion of the spike itwill act in the manner of a lever, so that when its up- 'p'er end istilted in one direction, its lower Cend will'be tilted in thewpositedirection Q and the toothed edges be rmlg em- -40 bedded in the tie onthe op osito si es of l the main or bodydportion of e spike, there- T,by serving to ho the spike securely in lace 1 -imuch more eectually thanif the loc g member were to lie in its operative osition 4,5 entirely toone side of the spike. t is oi course, immaterial just where the pivotint be relative to the locking memr. It might be located at theapproximate point illustrated in the accompanying draw- '50 ing, or atany other desired point. Manifestly the rivet may be of any desiredsize, so as to eii'ectuall brace the locking member :Liand strengthen earts and prevent them from becoming acci entally separated.

lm that form of the invention illustrated is .fin Figs. 1, 2, and 3, itis to be particularly w noted that the recesses in the side saggi--thebody portion form upwardly racing l shoulders at the tapered int or toeto pro '60 duce a barbed point.

l feetfi'aliy prevent the accidental withdrawal .ence not only does d..firmly embedded the tie and Kef-i es of the rivet ivlii;Z pivotallyconnects the lockscarso ing member with the body portion of the spinetend to prevent the spike from being withdrawn by breaking theconnection between the two parts, but the barbed point also assists insecurely holding the spike in the tie, even should the connectionbetween the locking member and body portion of the spike be broken.

Having thus described the invention, what is claimed as new is:

l. A spike, comprising a body portion, a locking member pivotallyconnected thereto and formed with a tooth, and means carried by saidlocking member adapted to engage a base iiaiige o? member may be rockedto an inclined position relative to the body portion.

2. A spike comprising a body portion and a locking member ivotaliyconnected thereto intermediate o its ends, said locking member beingtoothed on its edges and embodying means at its upper end designed toengage the base flange .o a rail for the pur` pose specified.

3. A spike, comprising a body portion, a locking member pivotallyconnected thereto and provided at its u per end below the head of' thespike wit means adapted to engage the base tlang'e of a rail for the purose ecied, the ocking member being orme with oppositel facing toothededges adapted to be projecto beyond the body portion of the spike by andupon the engage-V mentif sich means with thediiange. d-

5. A spike, comprising a body portion, a locking member pivotallyconnected thereto and provided at its upper end belowthe head of thespike with a forwardly 1dpro ecting portion adapted to engage e use angeof a rail, the lockinfr member d' formed with a tooth adapted toprojecto beyond the body portion of the spike by and upon the engagementwith said flange, the locking member being formed at its u p r endopposite the projecting portion w1 a luv', for the purpose set forth.
